Alcohol Abuse vs. Crime Rates

Brainstorming

• low income vs. delayed retirement
• hours of sleep vs. work habits
• abuse of drugs vs. students average
• family violence vs. alcohol abuse
• spousal abuse vs. divorce rate

Question

• Does alcohol abuse have a correlation with crime rates in Canada? (2003-2008)

VS.

Variables

• Independant- alcohol consumption (x)
• Dependant- crime rates (y)

Hypothesis

• I believe that the more alcohol you consume to the point of abuse, crime rates will increase.

Information

• When people consume alcohol to the point of abuse, they have less control over their actions, which could cause them to make reckless decisions. I'm trying to prove this statement.
